Until the printer was in final assembly, I didn't realize how far forward the Y bed travels.įOLLOWUP COMMENT #2: The Y axis build video doesn't involve the Y idler in the belt alignment. I also trimmed back the excess belt to make sure it didn't reach to the bearings in the Y idler.

As shown here, that zip tie would catch on the bracket holding the Y idler at the front of the printer.

I ended up with a belt approximately 26-1/4 inches between holes in the two aluminum spacers.įOLLOWUP COMMENT #1: In adjusting the Y endstop switch, I determined that the uppermost zip tie in the picture had to be moved closer to the aluminum spacer belt mount. Washers were put on opposite sides because of the mysterious offset between the brackets on the Y-bed and the brackets on the Y-idler. I used 3/8-inch long aluminum spacers, filling the remaining gap in the mounting brackets with two flat washers placed on the side opposite from where the two washers were put on the Y - idler. Similar to what I did on the X axis belt, I wrapped the Y axis belt around some aluminum spacers and doubled up on the zip ties.
